Toyo Proxes TR1 (new) vs T1R(old)
Discussion
Just purchased a Toyo Proxes TR1 for my Lotus Excel. However I now realise that the three other existing tyres are Toyo Proxes T1Rs. Thing with the new TR1 is that it is labled inside/outside rather than being directional and that then means that the tapered grooves are running in the wrong direction when fitted on the nearside.
Is it ok to run with one TR1 and the other three T1Rs? Are these new TR1s much the same as the old TR1s?

Are you sure it is not directional and 'sided'? You may have bought the wrong tyre if it is. Are the tread pattern in the form of a V? If so, they must be the correct direction to work.

Is that even a thing? Tyres will either be directional or will have an 'inside' and an 'outside'. If they were both directional and marked 'inside' and 'outside', manufacturers would have to manufacture left and right handed tyres!Says in the OP the tyres are labeled 'inside' and 'outside'.
The OP's question has been coming up for years, especially since the Uniroyal Rainsport 3s came out which had an assymetric tread design which 'looked' directional. If they say 'inside' and 'outside' on them, that is the way they must be installed. I don't think manufacturers will be supplying tyres which only work properly on one side of the car, or which have been incorrectly marked as non-directional. If the rotation arrows are pointing in the right direction, or the 'outside' label is showing on the outside, the tyres are correctly fitted.
As for how the TR1s will match with the T1Rs, The T1Rs are a really old pattern so I'd expect brand new TR1s to offer much more grip than T1Rs which are many years old. For this reason the usual advice is that the new tyres should be installed on the back of the car. Also I'd make sure that at the very least the tyres should be matching across the axles so I think OP needs to buy at least one more TR1. Probably three when they find out how old the T1Rs are.

by mistake I ended up with T1Rs on my front axle and TR1s on my rear. I hadn't realised there was a new tyre and didn't spot the subtle naming difference. I'd say the older T1Rs are as bad as people report and that the new tyre is much better. I certainly wouldn't mix across the axle or put the older tyre at the rear!

Yes it is, asymmetric tread pattern meaning inside and outside are fixed, then add directional tyres. I had some a few years ago, needed to ensure you bought the correct sided tyre at order time. Says in the OP the tyres are labeled 'inside' and 'outside'.
